i965: Print instructions' children during scheduling debugging.
Useful for tracking down problems in dependency calculations.
Scheduling debugging now prints:
clock 2, scheduled: linterp vgrf5, hw_reg2, hw_reg3, hw_reg0,
child 0, 53 parents: fb_write (null), (null), (null), (null),
child 1, 2 parents: tex vgrf4, vgrf5, (null), (null),
child 2, 52 parents: placeholder_halt (null), (null), (null), (null),
clock 4, scheduled: linterp vgrf5+1, hw_reg2, hw_reg3, hw_reg0+16,
child 0, 52 parents: fb_write (null), (null), (null), (null),
child 1, 1 parents: tex vgrf4, vgrf5, (null), (null),
now available
child 2, 51 parents: placeholder_halt (null), (null), (null), (null),
